Abstract

Otoacoustic emissions (OAEs) and Auditory Brainstem Responses (ABRs) are objective diagnostic tools used in audiology to provide information regarding pathologies of the auditory system. Several factors, besides hearing loss, can affect OAEs and ABRs. Internal factors include body temperature and internal noise of the individual, whereas some external factors include environmental noise, probe placement, and equipment parameters. The purpose of this study was to provide more information on the effects of body temperature on Distortion Product Otoacoustic Emissions (DPOAEs) and tone-burst Auditory Brainstem Reponses in the pigmented rat. Results indicate that there was no significant effect of body temperature on either the amplitude of the DPOAEs or the threshold of the tone-burst ABRs.
